HOSE OR PIPE MENDER.

SPECIFICATION forming part of Letters Patent No. 719,817, dated February3, 1903.

Application filed May 16,1902.

To all whom it may concern:

Be it known that I, REINHART F. KUNZE, a citizen of the United States ofAmerica, residing at Detroit, in the county of Wayne and State ofMichigan, have invented certain new and useful Improvements in Hose orPipe Menders, of which the following is a specification, r eferencebeing had therein to the accompanying drawings.

This invention is designed for mending leaky hose or pipe, and isespecially applicable for hose or pipe in which compressed air isconveyed to pneumatic tools-as, for instance, pneumatic riveters, whereinjury to the hose is of frequent occurrence as a result of dropping hotrivets on the hose; and it is the object of my invention to provide asimple, cheap, and effective device completein itself which can bereadily applied by the workman himself without the use of special toolsor other appliances to close a leak in the hose or pipe.

To this end my invention consists of a tubular clip adapted to partiallyencircle the hose or pipe and provided with a clasp arranged to clampthe open ends of the clip tog'ether and of a pad held within the clipand adapted to seal the break in the hose or pipe, all arranged andoperating as more fully hereinafter described, and shown in theaccompanying drawings, in which Figure 1 is a perspective view of myimproved device, the parts being detached. Fig. 2 is a horizontallongitudinal section through the clip. Fig. 3 is a vertical longitudinalsection through the clip at right angles to Fig. 2. Fig. 4 shows asection of hose or pipe to which my device is applied. Fig. 5 is aperspective view of a modified construction detached.

A represents a tubular clip made of tin or other thin sheet metal andprovided along the longitudinal edges with outwardly-bent portionsforming hooks a.

13 represents the clasp, made of tin or other thin sheet metal andprovided along its longitudinal edges with inwardly-bent flanges formingbooks I), so arranged that the clasp is adapted to secure the open endsof the clip together when the hooks of one are engaged Serial No.107,599. (No model.)

with the hooks of the other, the two parts when united forming a"complete tube, the inner diameter of which should be about equal orslightly less than the exterior diameter of the hose or pipe to bemended.

The clip is provided with a recess 0, adapted to form a seat for a pad0, which may be of rubber for mending hose or of lead for mending pipe.This pad in case of being rubber or other like material may be glued orotherwise fastened in this recess to prevent it from falling out, or incase of its being lead or other like material it may be for a likepurpose soldered in or otherwise fastened. This pad projects into theinterior space of the clip and forms the sealing medium for closing theleak in the hose or pipe by applying the clip over the defective portionof the pipe or hose by springing the edges apart and then hooking theends of the clip together by means of the clasp.

In order to press the pad firmly against the leak in the hose or pipe,the hooked edges of the clip or pad, or preferably of both, are made toslightly converge toward each other either the whole length or for aportion of their length in such manner that the open ends of the clipare forcibly drawn together by driving home the clasp, and therebypressing the pad firmly against the leak. I also find it desirable,especially in case of menders for iron pipe, to lock the clasp inposition against accidental displacement. To this end I preferably formthe hooked flanges a of the clip, one or both, with looking projectionsd, and correspondingly therewith form the hook flanges of the clasp withlockingrecesses formed by filing or cutting away a corresponding portione at the outer edge.

While I have described my invention as a hose or pipe mender, it isobvious that it may be applied to other uses, such as for clamping hoseto coupling members, the.

My device has been found in practice to answer well for the purpose forwhich it has been designed and forms a useful article of manufacturewhich hasdone away with many of the inconveniences connected with theuse of pneumatic tools, where injury to the hose is difficult to avoid.

It is obvious that my device may be used as well for a hose-clamp as amender, and in Fig. 5 I have shown a modified construction with thesealing-pad omitted, the opposite edges of the sliding member B beingparallel, while the bent lips or hooks on both the clip and clasp aretapered to exert the necessary wedge action to securely clamp the partstogether.

What I claim as my invention is 1. As a new article of manufacture, ahose or pipe mender composed of a tubularlyformed sheet-metal clipadapted to partly eucircle the pipe or hose and have an opening betweenits longitudinal edges for introducing the hose or pipe by springing theedges apart, said edges being formed with hookflanges, a sealing-padsecured in a recess in said clip between the open ends and projectinginto the interior space in the clip, and a locking-clasp havinghook-flanges adapted to engage with and draw the edges of the cliptogether, and locking projections on the edges of the clip adapted toengage into recesses formed in the edges of the clasp.

2. As a new article of manufacture, ahose or pipe mender composed of asplit sleeve adapted to be clamped around the hose, of a sealing-padsecured in said sleeve and projecting into the interior space of saidsleeve.

3. As a new article of manufacture, a pipemender composed of a tubularmember adapted to be clamped around the pipe, of a sealing-pad of softmetal secured in a recess in said member and projecting into theinterior space of said member and conforming to the shape thereof.

In testimony whereof I affix my signature in presence of two witnesses.
